Using Java Operations

A Java-based operation includes inputs, outputs, results, and one action.

Java-based actions are read only and you cannot add\copy\edit them. They can only be found under the Dependencies panel, or imported using Source Control Management (SCM) (you cannot edit and copy them even if they are located in the Projects panel). You can use them as steps in flows by dragging them from the Dependencies or the Projects pane.

Use the Operation Editor to display information about an operation.

ClosedJava Actions

Java action contain the following elements:

  • GAV. GAV is short for "Group, Artifact, Version". The GAV coordinate standard is the foundation for how Maven manages dependencies.

    • A group identifier groups a set of artifacts into a logical group
    • An artifact is an identifier for a software component
    • The version of a project follows the established convention of Major, Minor, and Point release versions.
  • Class Name. This is the class within the GAV where the running method can be found.
  • Method Name.This is the method to run within the action.
ClosedView the properties of a Java operation

  1. Double-click an operation in the Projects or Dependencies pane to open it in the Operation Editor as read-only.

    The Java Action view displays the GAV (group, artifact, version), class name, and method name that define the Java action in the operation.

  2. Click the Properties button to display the Properties view.

    You can return to the Java Action view, by clicking either the Java Action button or the Back to Action button.

  3. Under the Inputs tab, view the inputs that the operation receives. Each input in an operation has a value that can be set in a number of ways. It may be a constant value, a python expression, the value of a flow variable or system property, and more.

    See Inputs.

  4. Under the Outputs tab, view the values returned from the Java code. They will be sent back to the calling step.

    The Outputs tab lists any information that needs to be sent back to the calling step. The outputs are a list of key:value pairs where the key is the name of the output and the value is the expression to be returned, blank, constant, or more.

    See Outputs.

  5. Under the Results tab, view the results that will be returned to the calling flow.

    See Results.

  6. Under the Description tab, view a description of what the operation does, if one was entered.

  7. To view the code behind the operation, click the Show as Text button. A text box appears, displaying the code.

  8. Click OK to close the text box.
